An ice island bigger than the size of Birmingham has broken off from a glacier
in Greenland in the biggest such event in the Arctic in nearly 50 years.

The huge island, which is 100 square miles (260 square km) in area with a
thickness up to 600ft (340m) — half the height of the Empire State building
— broke off from the Petermann Glacier, one of the two largest glaciers in
Greenland, on Thursday.

Greenland’s ice has been under intense scrutiny by scientists seeking to
understand how fast it will react to the warming climate.
